Overview of Vinci
A comprehensive multidimensional fluorescence spectroscopy software program designed to enhance the capabilities and performance of ISS spectrofluorometers.
Compatible with ChronosBH, ChronosDFD, and PC1.
Vinci offers unparalled performance to the end-user through three distinct features
Instrument Control
Vinci provides full control of all the automated instrument components, including shutters, polarizers, sample holders, monochromators, and enables the integration of external devices such as stopped-flow apparatus, titrator, and temperature bath. Vinci's remote interface allows ISS Support Personnel to access any instrument in the world via internet and conduct a remote diagnostic check-up.
Data Acquisition
Vinci offers a variety of data acquisition options (spectra, lifetime, kinetics, titrations) through built-in, easy-to-use, routines and allows the user to generate, store and rerun custom-designed data acquisition protocols. Data are stored in ASCII format for convenient access from other software packages.
Data Analysis
Vinci's fast fitting routines allow the user to retrieve multiple decay times and rotational correlation times, to obtain time-resolved spectra with picosecond resolution and to separate steady-state spectra of up to three components in a mixture using the phase- and modulation-resolved spectra measurement option. Other operations include smoothing, derivative, calculation of area and arithmetic between files. A superb graphical interface generates and displays 2D and 3D plots that can be exported in presentation-ready formats. A report can be saved in Word or PDF format.

Data Format
- The data files are stored in an accessible text (ASCII) format.
- The experiment data file, or raw data file, includes the information about the experiment protocol and, as such, it can be re-loaded to rerun the original experiment.
- Experiment data files cannot be overwritten; once an experiment data file is modified, the new file is stored as analysis data file. Experiment files and Analysis files are identifiable through their different extensions and icons.
